After experiencing a variety of shortages, crises, and inefficiencies in the status quo of the procurement and distribution industry, I undertook the responsibility of building an interface for large organizations to abstract away uncertainty throughout their supply chain under most conditions.

We are focused on building a framework from which our teams of professionals on the ground can provide a new generation of procurement support and professional services for supply chain critical organizations around the nation.

We understand that the marketing process of critical supplies is a matter of national security and public safety. In this, we found our passion and mission: developing technologies, supplier networks, and platforms for the organizations that need it most.
